What has happened here?

Tuesday, 17th September 2013

Some poor misguided firewall / router / voodoo packet forwarding aparatus has decided to let this packet out:

*mangle DROP: IN=eth0 OUT= MAC=00:14:85:17:09:8e:00:23:5e:7c:ba:1b:08:00 SRC=0.0.0.0 DST=202.21.137.10 LEN=76 TOS=0x00 PREC=0x00 TTL=251 ID=19777 PROTO=UDP SPT=65535 DPT=123 LEN=56

Theres a heap of drops in the logs for rfc1918 addresses, but 0.0.0.0 is a new one.
